TO ALL WHOM IT MAY CONCERN:

Be it known that LEMANUEL-RABER, of Lake, in the countyci Stark, andState of Ohio, havcjinventecl certain new and useful Improvements inHay-Forks; and I do hereby declare, the following. toho a full, clear,

and exact description of the same, refcrence being had to theacconipanying drawings, makinga part of this specification, in which- IFigure 1 represents the hay-fork in question when holding and sustainingor raising its load or charge of hay, and

Figure 2 representsits position when it has been tripped andhas/discharged its load.

Figure 3 represents, detached, the trigger by which the fork is held inthe position shown in fig; 1, and tripped and allowed to open, as shownin fig. 2.

Similar letters of reference, where they occur in the separate figures,denote like parts of the apparatus in all of the drawings. i

My invention'r elates to a hay-fork for raising large quantities of hayat a time the tinedor holding-jaws of which are locked when insertedinto the hay or other article to be raised up by it, and which aretripped and drawn apart to discharge its load'by the operator simplypulling a cord or line co'nnected with a trigger.

To enable those skilled in'the art to make and use my invention, I willproceed to describe the same witl reference to the drawings. i

The jaws or forks A A are in the form of grappling-jaws, and are pivotedtogether at a, so as to swing towards or from each other; and at a isalso hung a clevis, b, which unites these forks or jaws to atriggerblock, B, in which is pivoted, at c, the trigger C, which has acord or line, d, connected to it, by which it may be operated.

To the block 13 is connected a bar, D; the upper end of which has a loopor guide, e, in it, through which a second bar, E, slides, said secondbar E carrying a spring-hook, E, which, when in a certain position, as

shown in fig. 1, is locked or held by the trigger a, the hook takingagainst the shoulderf-on said trigger.

To the upper end of the bar E is connected the rope by which the forkand its-load are raised; and to this part of the bar E, viz, itsppperend, are connected two cords, ropes, or lines gg, one extendingtoeach of the pair of grappling-forks A A. i

The operation of the fork is as follows:

In closing the forks upon the hay, the linesgg draw down the bar Efandthe spring-hook F, taking against the trigger c, locks itself there byrunning under the shoulderfof the trigger, 'as shown in fig. 1.

The fork, with its load upon its tines, is now ready to be raised to anydesired height, and when it is at the place where it is to be deliveredor dropped, the operator simply pulls upon the cord at, which causes thetrigger C to throw out the hook F,'and the weight upon the forks causesthemto drop, and in so doingthe cords or lines g g, which are fastenedto the bar E, which remains in its suspended position, draw the forksout hi the load or charge of hay and allow it to drop.

Having thus fullyideseribed my invention, what; I claim therein asne\v,-and desire to secure by Letters Patent, is-- I In combination withthe pivoted forks A A, the trigger C, hook F, and lines or cords g,connecting said forks with the bar E, so that the forks may enter andhold and carry the loader charge of hay upon their tlIlSyflDd drop it atthe placeof delivery, substantially as herein described andrepresentedaEMANUEL RABER.
